The sorting tray teaches a child how to organise and sort objects. Not only is the child learning to sort objects by colour, but they are also improving visual perception, colour discrimination, coordination, fine motor skills and concentration. This activity will also help to develop numerical skills along with grouping similar objects together. The set is made of natural Beechwood, containing no harmful substances, with smooth surface, no burr and edges, which are comfortable to touch. They are also sturdy and not easy to break.
